VJ 628 Basic Operations

Inspecting the Cutter Blade:

 

Single shift users: Inspect paper cutting edge and blade for wear every 6 months or as needed. 
Multiple shift users: Inspect paper cutting edge and blade for wear every 1440 hours or as needed. 

Inspect paper for jagged cut edges, blade wear or if paper dust begins to
collect internally around cutting areas and capping station.
Replace as needed with VJ-628 Sheet Off Knife - Cutter Blade


Inspecting the Media Holders:

 

Inspect Media Holders daily.

Inspect holders for bent edges, abnormal wear or if ink and paper dust collects underneath.
Slide back and forth to clean area underneath.
Do Not use printer if holders are bent as headstrike may result.

Replace as needed with VJ-628 Media Holder Assembly


Monitoring Ink Levels:

 

Check ink cartridge levels at the beginning of each production cycle and periodically as needed.

Inspect the ink levels in the ValueJet Status Monitor to determine if a new ink cartridge will be needed soon and plan ahead with new cartridges ready to use before the ink is depleted. You may obtain additional cartridges through your authorized Sawgrass dealer.

(As demonstrated in the Getting to know the ValueJet Status Monitor video.)

Tip: The ValueJet Status Monitor updates by default when the Printer Info button is selected.



To keep real-time information on ink / waste ink levels, select the Auto Printer Information tool available in the printer status window of the ValueJet Status Monitor. When selected (each time you start VSM), this will automatically refresh the information in your desired intervals of 3, 10, 30 or 60 seconds.



 

Monitoring Waste Ink Levels:

 

Check waste ink level at the beginning of each production cycle and periodically as needed.

Select Reset Waste Ink button only when physical tank has been emptied to avoid overspill into the printer.
A container with the ability to hold at least 1.4 Liters will be needed.
(As demonstrated in the Emptying the Waste Ink Tank on the Sawgrass VJ-628 video.)


Performing a Nozzle Check:
 

Perform a nozzle check at the beginning of each production cycle and periodically
as needed between large job queues. 

Avoid printing when nozzles are missing and perform a short normal or long clean in accordance to the severity of any nozzle loss. 

(As demonstrated in the Getting to know the ValueJet Status Monitor video.)


Note:  In extremely rare cases where nozzles are not retrieved using the advised short, normal or long clean, or if you have discovered air bubbles in the ink lines, you may consider performing a Little Charge, followed by a normal clean.

Be advised:  Little charge uses a considerable amount of ink and is primarily used to flush ink lines and the print head.
This function should not be used on a normal basis as a cleaning tool as ink cartridges will deplete faster.

Printer and Paper Alignment:

 

Alignment checks should be performed each time you change your paper/media roll,
move the printer to another location or if blurry image output is present.

It is important to run alignments on your printer to avoid undesired output such as blurry images or ghosting text. These alignment tools are performed using the Adjust Print and PF Adjust function located in the ValueJet Status Monitor.
(As demonstrated in the The Sawgrass VJ-628 Start-Up Guide as well as the Getting to know the ValueJet Status Monitor video.)


Recommended Environmental Conditions:

 

Inspect environmental conditions before and periodically during print production cycles.

Multiple 8-Hour Shift Users: It is important to understand that environmental conditions at 11am may be vastly different than conditions at 11pm. Log temperature and humidity of each shift to prepare, adjust and maintain accordingly.
(As demonstrated in the The Sawgrass VJ-628 Start-Up Guide)


Splitting Function Settings

The printer will always spit into the flushing box pad before every nozzle check and before printing starts. However, you may set the spitting count manually using the Advanced Settings Tab in the VSM software.

With Sawgrass inks, it would be acceptable to set the spitting Pass Count to 25 (a) and Update (b).
The print head will make 25 print passes before returning to the flushing box to spit, as a maximum limit without compromising the functionality of the printer or print head.

If you see more nozzle loss with this adjustment, reduce your pass count from 25 down, until you find the best pass count suited for the environmental conditions of your area.


The Status Information Screen:

 

Check the Status Information Screen in the ValueJet Status Monitor at the beginning of each production cycle and periodically as needed for any alerts or error messages or if printer begins to beep at any time.
(As demonstrated in the Getting to know the ValueJet Status Monitor video.)

Note: Do not ignore messages. If you have questions on any error messages displayed, contact Sawgrass Tech Support for assistance.
